Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed June 27,1906. Serial No. 323,726-

To all whom it may concern:

Be it known that we, HENRY W. GALE and THoMAs' ORoLL, citizens of theUnited States, residing at Miller, in the county of Hand, State of SouthDakota, have invented certain new and useful Improvements in Ohafe-Irons; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention has relation to what are commonly known as chafe ironsfor guarding the bodies of vehicles against wear and protecting themagainst mud being lodged upon them by the wheels in turning, when thetire is almost certain in all cases to rub against and chafe the lowercorner of the vehicle body, rendering it unsightly and rapidly wearingit away; besides this, the. wheel is liable to become cramped under thebox or body and overturn the vehicle or do other damage.

It is the purpose of the present invention to provide a chafe or rubiron that will effectively guard and protect the vehicle body, and, byreason of its peculiar constructive character obviate any liability ofthe parts cramping with the resultant mischiefs mentioned.

It is also the object of the invention to provide a chafe-iron that willbe durable in the highest degree, not only because of its substantialconstruction, but by reason of the reversibility of some of the parts,which practically doubles its lasting qualities.

The invention consists of novel parts, new combinations, and arrangementof parts, and the novelty of the device as a whole, all as is clearlyshown in the annexed drawings, and as will be described in detailhereinafter and finally pointed out succinctly in the subjoined claims.

Of the said drawings, Figure l is an end iriew with the wagon box insection. Fig. 2 is a longitudinal section through the roller. Fig. 3 isan elevation of the invention in place.

Similar figures of reference designate similar parts or features, as thecase may be, wherever they occur.

In the drawings, 10 designates the supporting irons of which there isone at each end of the complete device, and each of which is providedwith a bearing 11 for the end of the pintle or rod 12, which isconstructed as a bolt, provided on one end'with a head 13, andscrewthreaded at the other end for the reception of a nut 14, the saidpintle passing through the bearings 11 of the support inside of the saidnut 14 and head 13.

Between the hearings on the pintle is a rotary sleeve 15, in the form ofa roller, against which the wheel of the vehicle comes in turning, andwhich constitutes the immediate protecting and anti-cramping means whenthe device is secured to the lower edge of the vehicle body, which isaccomplished through the medium of the arms 16 that extend at rightangles from the bearings 11. The said arms 16 have holes made throughthem for the reception of the shanks of the attaching screws, which areturned through or into the sides or bottom of the vehicle body or box,all as will be completely understood without further explanation.

At their outer sides the bearings or knuckles 11 are cut away slightly,as at 17, for the head 13 of the pintle or rod 12, on one side, and forthe nut 14 on the other side. A shoulder or offset 18 is formed on eachside of the cut-away part 17 against which the flat sides of the nut andhead of the bolt bear, most of the time, and this constitutes a lock forthe nut and bolt, so that it is not liable to turn off accidentally, andthus loosen the nut bolt and roller.

To cause the shoulders 18 to take over the head 13 and nut 14 and holdthem in place, the parts will be adjusted before one or both sets of theangular arms 16 are secured to the body of the vehicles.

The device can be shifted from place to place, within the limits of itsconstruction, so that when it becomes worn in too great a degree in oneposition it can be changed so as to bring a new point into place toreceive the bearing of the wheel. Again the sleeve or roller 15 caneasily be taken off and changed end for end to bring a new surface orline of bearing into place, and in this way greatly prolong the life orusefulness of the device.

Thus far the description has been directed to the attachment of theinvention to plane or right angular corners of a wagon-body; it may,however, be applied to bodies or parts having a different shape, in theperformance of the same function. In this case the only change that willbe made will be in the form of the arms 16, that will be bent to suitthe form or the surface on which they bear. For example, in its use ontraction engines it may be secured to the boiler to protect it againstwear or damage by the front wheels in short turns. Without changing theform of construction of the roller, the arms or brackets 16 may becurved, so as to fit on the boilers, and this change in shape may bemade in other instances where circumstances call for it.

Other changes may be made in the form and arrangement of partsconstituting the invention, within the scope of mechanical skill withoutdeparting from the general nature or spirit of the invention.

What is claimed, is:

A chafe iron comprising in its construction a pintle, a sleeve rollerthereon, supports consisting of the right angular arms or brackets,provided at their angular points With bearings for the pintle, thelatter having a head on one end, and the other end being screwthreadedand having a nut turned thereon, the said bearings being cut-away ontheir outer sides forming shoulders against which the head and nut onthe pintle bear to lock them against turning.

In testimony whereof, I aflix my signature, in presence of twoWitnesses.
